Gmail and other G Suite services have a powerful search utility built inside. In the top bar, you can find a search bar, which will be available in all of the G Suite services and helps you locate content you need. (Mail, files, folders, text, etc.)
Write the searched word to the search bar and press Enter or click Search. You will receive the search results.
Please note, that you can't search with parts of a word or use asterisk (*).
You can search in example straight away with senders name. As you start typing, Gmail will suggest available senders to you. In case you have just started using G Suite, it will take a while for Gmail to suggest old contacts.
You can specify the search by clicking the small triangle on the search bars right side.
